Hi, Allen. I'm sure I read the article on the Beat. Before I responded here, I went over there and tried to find it, but, I'm sorry, I couldn't find it.
In doing a web comic, I don't see it as any harder than uploading files to a site.
In the article I read, I was surprised to find out that there seemed to be a steep cost involved in preparing files for the Kindle tied to file size. And I forget exactly how it worked, but I seem to recall that color increased the cost, just like it does with print.
It could have been on another site, like Bleeding Cool, but I don't remember.
